Quantum Nanomaterials for Qubits and Quantum Sensors : Concept Overview

Quantum nanomaterials have been extensively investigated over the past few decades, as these atomic-scale systems exhibit discrete quantum states. Electron spins in both ground and excited states can be exploited to represent quantum information, typically encoded as |0⟩ and |1⟩. In this rapidly advancing field, various quantum states have been explored using a wide range of materials, including superconductors, nitrogen-vacancy centers in diamond, and single-molecule magnets, etc. In this special issue, several recent and significant studies on quantum nanomaterials are reviewed, with a focus on their potential applications in quantum sensing and quantum bits (qubits).
